Samsung PM1643 SAS vs PM883 SATA for Enterprise SSD RFQs

Procurement note: Representative examples support identification and procurement planning. Final model, condition, compatibility, evidence, availability, and quotation remain order-specific.

SECTION 01

Decision summary

The reviewed PM1643 example is a SAS 12 Gb/s SSD and the reviewed PM883 example is a SATA 6 Gb/s SSD. That protocol difference requires a controller, backplane, bay and carrier review; similar capacity or enclosure does not establish a valid replacement.

SECTION 02

Preserve exact identity

Record the full installed and requested identifiers, not only PM1643 or PM883. The photographed examples show PM1643 960GB and PM883 3.84TB labels and remain representative of those exact catalog records.

SECTION 03

Interface and form factor

Both reviewed examples use a 2.5-inch enclosure, while their documented interfaces are SAS and SATA. Physical size alone does not establish the required signaling path, connector behavior or server support.

SECTION 04

Complete storage path

For PM1643, identify the SAS controller, backplane, bay and carrier path. For PM883, identify the SATA controller, backplane, bay and carrier path. Record the server model and any OEM or firmware requirement for the exact request.

SECTION 05

Quotation evidence

Request label evidence and protocol-appropriate diagnostic output for each quoted unit or an agreed sample. Define target condition, test scope and packing inputs without treating a catalog photograph as quoted-unit evidence.
